The various embodiments of the present disclosure relate generally to electric utility meter instruction detection systems and methods.
Electric utility meter housing intrusion poses a significant challenge for electric utilities to detect. This practice typically aims to bypass metering systems, underreport consumption, or alter readings to reduce electricity bills. Service manipulation not only results in financial losses for utilities but also undermines fairness of billing processes and creates safety hazards for the general public. To combat socket wiring manipulation, utilities employ various strategies, including advanced metering technologies, intrusion-evident seals, periodic inspections guided by data analytics to detect suspicious patterns. Additionally, legal measures and penalties are enforced to deter individuals from engaging in this illegal activity and to protect the stability and sustainability of the electricity distribution system.
Many conventional detection systems primarily rely on basic threshold-based algorithms or electronic detection of a meter being removed from the meter socket or meter losing power. Current diversion techniques, however, often involve dismantling the meter housing without removing the meter from the meter socket, making these conventional techniques ineffective. As techniques evolve, there is a growing need for more advanced, intelligent systems that leverage additional sensors in the meter.
An exemplary embodiment of the present disclosure provides an electric utility meter tampering detection system, comprising an electric utility meter housing, an electric utility meter located in the housing, and a sensor disposed in the housing. The sensor can be configured to detect the presence of light entering the housing from an area external to the housing.
In any of the embodiments disclosed herein, the sensor can be disposed between the electric utility meter and a meter socket.
In any of the embodiments disclosed herein, the system may not contain an internal light source configured to direct light to the sensor.

The components, steps, and materials described hereinafter as making up various elements of the embodiments disclosed herein are intended to be illustrative and not restrictive. Many suitable components, steps, and materials that would perform the same or similar functions as the components, steps, and materials described herein are intended to be embraced within the scope of the disclosure.

As shown in
The housing 105 can house an electric utility meter 110 in the interior volume. For example, the housing can include a socket 106 configured to receive the meter 110. For purposes of illustration, in
The system can further comprise one or more sensors 115a 115b disposed in the housing 105. The sensors 115a 115b can be configured to detect the presence of light entering the housing 105 from an area external to the interior volume of the housing 105. The sensors 115a 115b can be many different sensors known in the art for sensing and/or measuring a level of light, including, but not limited to, a photosensor, a photodiode, and the like.
The one or more sensors 115a 115b can be disposed at many different locations within the housing 105 in accordance with various embodiments of the present disclosure. In some embodiments, as shown in
In any of the embodiments disclosed herein, the system may not contain an internal light source configured to direct light to the sensor (e.g, a LED). This can help ensure that light detected by the sensors 115a 115b is indicative of tampering and/or arcing (i.e., abnormal operation), as opposed to routine operation of the meter 110.
In any of the embodiments disclosed herein, the system can further comprise a controller 120 configured to receive a signal from the sensor 115s and/or 115b indicative of the level of light. The controller 120 can be further configured to generate an alert when the level of light is above a predetermined threshold. In some embodiments, the predetermined threshold can be relative to a previously measured level of light. For example, in some embodiments, the controller 120 can detect changes in the level of light and generate an alert when the change in the level of light is above the predetermined threshold.
The controller 120 can be many controllers known in the art, including, but not limited to, microcontrollers, microprocessors, computing devices, and the like. In some embodiments, as shown in
In some embodiments, the predetermined threshold can be dependent on one or more parameters that affect the level of light that may be expected external to the housing 105, including, but not limited to, a current time of day, a current date, sunrise and sunset data, and/or the like. For example, the predetermined threshold may be lower at 3:00 AM than at 3:00 PM because it would be expected that the level of light naturally present outside the housing at 3:00 AM would be lower than at 3:00 PM.
In some embodiments, the controller can also monitor the length of time that the present of light is detected (including, e.g., a length of time that the level of light increases as compared to a prior measurement) to determine if an alert should be generated.
As discussed above, the system can be useful for detecting when the meter housing 105 has been tampered with to access the terminals 107, even when the meter 110 is not removed from the socket 106. For example, if the meter housing 110 is opened to access the terminals 107, light from the environment outside the housing 105, e.g. sunlight of light from a flashlight, will illuminate the sensor 115a 115b. In response, the sensor 115a 115b can generate an alert indicative of meter tampering.
In some embodiments, one or more sensors 115a 115b can also determine wavelength(s) of light incident on the sensors 115a 115b, which can be used to determine whether tampering has occurred. For example, the wavelength(s) incident on the sensor 115a 115b can be used to determine whether light from a non-natural light source is present within the housing 105 (e.g., red, blue, or green flashlight, torch, candle, LED, incandescent lamp, etc.).
The system can also be used to generate an alert indicative of electric arcing in the utility meter housing 105. For example, the electric arcing, e.g., between terminals 107, or a terminal 107 and another conductor, can generate light that is not normally present in the housing 105. This light can be detected by the sensors 115a 115b and analyzed to determine that the light may be associated with arcing (for example by analyzing the level and/or duration of the light). To determine if arcing is present, in some embodiments, the controller 120 can also monitor temperature from sensors (not shown) within the housing and/or voltage/current data provided by the utility meter.
The present disclosure is not limited to the use of any number of sensors. Rather, one or more sensors can be used to measure light and/or temperature, in accordance with various embodiments of the present disclosure. For example, in some embodiments, as shown in
In some embodiments, the sensors 115a 115b (or another sensor) can further measure a temperature within the housing 105. The temperature inside the housing 105 can also be indicative of a tampering and/or arcing. For example, a sudden temperature change can be indicative that the housing 105 was opened and exposed to air from the external environment. Similarly, arcing can generate additional heat inside the housing 105.
In addition to tamper detection systems, some embodiments of the present disclosure provides methods of detecting electric utility meter tampering. As shown in
In some embodiments, the method can further comprise transmitting a signal to a remote computer (e.g., server or remotely located controller). The signal transmitted to the remote computer can be indicative of the level of light measured in the housing. The signal can be transferred many different ways known in the art, including but not limited to wireless transmission and wired transmission. Once the signal is received by the remote computer, the remote computer can process the signal (e.g., determine if it is above a predetermined threshold) and generate the alert.
